Note:
When SUN2000-60KTL-M0 is in the condition that it operates at rated and 1.1 rated output voltage,
it can output 66kW (when PF=1) or 66kVA at most.
When SUN2000-60KTL-M0 is in the condition that it operates at 0.9 rated output voltage, it can
output 59.4kW (when PF=1) or 59.4kVA at most.

Altitude（m）
Note:
SUN2000 inverter design safety distance in accordance with running at the altitude of 4000m and
below to avoid power de-rating. As altitude increases above 4000m, DC voltage de-rating of
SUN2000 should be taken into consideration and DC voltage drop in accordance with 13V/100m.
For SUN2000 inverter, the rated AC voltage will not be affected by the altitude.

Altitude（m）
Note:
The maximum working temperature is the ambient temperature below which SUN2000 can output
rated power without de-rating.
When the altitude rises, the cooling capacity of the inverters de-rates. So the internal temperature of
inverters in the high altitude area will be higher and severer than that in the low altitude area.
When altitude > 2000m, the maximum working temperature of SUN2000 should de-rate by altitude,
and it de-rates in accordance with 6℃/1000m.
